Sept. 29, 2004: Study Highlights Problems With Spa Pools As Legionella Source
LONDON - A study by London's Health Protection Agency has highlighted problems with spa pools (or whirlpool spas) as being a source of legionella and potential Legionnaires' disease because they are not managed and maintained properly.
The study surveyed over 100 spa pools in 88 locations, with 23 spa pools found to contain legionella bacteria. Sixteen of these had passed current accepted levels for routine microbiological parameters.
